THE stan OF BETHLEHEM.
Its History In Brief-A PoI uiar Fancy.
A Welcome Celestial Event.


A Welcome Celestial Event.
"Where can the Star of bethlehem be
found?' is the oft repeated question that
comes from many quarters. The fact is,
no such star is visible in any part of the
heavens. An observer with vivid i'm
agination fancied he had discovered this
long looked for star, and announced its
return in some journal of the day. The
paragraph was widely copied throughout
the country. The idea pleased the popu-
lar fancy, was received with almost UNI
questioning faith. and the sky was eagerly
scanned for glimpse of the star that
once shone over the humble dwelling that
enshrined the Redeemer of mankind.
Even the peerless Venus was impressed
into service, and was firmly believed to
be the sacred star once moro shining
upon the earth after wandering for ages
in the star depths.
The history Of the so called Star OF
Bethlehem IL briefly this Tycho Brahc,
Danish astronomer. discovered, il the
year 1879, an apparently new star near
Capli in Cassiopea. When first seen, In
November, it had attained the first mag
nitude. 1t increased rapidly in brilliancy,
until it rivaled Venus, and was visible ct
MONDAY. 1t began to diminish in bright
ness in December, and continded to fade
away until the following May, when it
disappeared from view.
Forty years later, when the telescope
was invented, n small telescope star was
found close to the spot where the Won
derful star was seen. 1t is still there,
and is probably the same. 1t is now
classed among variable stars, and is,
therefore, liable to blaze forth at any
time in the same extraordinary manner.
After classifying the star Us variable,
the next thing TO be done was to find out
its period of variability. Astronomical
records We're searched. and it was ascer-
tanned that about the years 1868 and $50
bright stars suddenly appeared near tho
same quarter of the heavens. 1t was,
therefore, classified as variable, with q
period Of about 800 years. Counting
hack three periods from 95G, the exact
period being uncertain, the star may
have appeared near tire time of the Chris
tan era. Some imaginative observer,
for this reason, christened it the Star Of
Bethlehem, and with scarce the shadow
of foundation the name has adhered to
Pilgrim Star. and among astronomers Us
the star of 1872
II the star he a variable, with q period
approximating to 500 years, it is now
due and liable to burst forth into sudden
brilliancy at any time. No celestial event
would I've more welcome to astronomers
The scientific world would bc wild with
excitement over the substantiation of an
ingenious theory and the confirmation Of
its hopes. Its first appearance, its exact
position in the heavens, its changes from
day 10 day, would he telegraphed all over
the country and minutely described in
the journals of the day. Tho advent of
a comet, spanning the sky from the
zenith to the horizon, would be of no DC
count in comparison with the blazing
star! Meantime the telescope star near
Caph i'm Cassiopea shows no signs of any
coming disturbance, and observers must
wait patiently for developments, remem-
herring that the 0aitburst will he sudden,
if it come.
1t is generally considered that the ex-
traordinary changes of light in stars, like
that Of 1879, are caused by sudden out
bursts of glowing hydrogen gas, which by
its own light and by heating up the whole
surface of the star causes the immense
increase in brilliancy. The spots, faculn
and rosy protuberances on the sun give
some idea, on a smah scale, of what may
he going on in other suns on much
larger scale. Fortunately. the now or
temporary stars observed by terrestrial
astronomers number only about twenty
four, an infinitesimal number when COM
pared with the boundless millions of stars
that shine with nearly unchanging bright
ness. Tho probability is, therefore, small
that our sun will be added to tho list Of
blazing stars. He will probably shine for
millions Of years to come, as he has shone
for millions Of years in the past, and if
observed from other suns and systems
will be classed as a variable, with period
of about eleven years, corresponding to
the cycle of sun spots. Scientific Amer
